RAILROAD-CAR.

Application filed April 17.

T all whom it may concern:

Be it known that l. Axis-11:5 Ilxxssx, of Philadelphia, in the State ofPennsylvania, have invented a certain new and useful Improvement inRailroad-Cars. whereof the had to the accompanying drawing.

1 My invention relates to a pressed steel car. having'a hopper bottomwith a central angularpartition whose oppositely sloping walls. areprovided with pivoted shutters. In the form of my invention hereinafterdescribed, said shutters are operatively connectet'l. with a screw nutforming acrosshead. engaged with a vertical screw threaded shaft whichis said crosshead and thus open and close said (anivcnient adjunctiveteatureo't' my invention is an adjustable sleeve. formed of telescopicsections surroundii'ig said screw shaft, arranged to exclude the dusttherefrom and to be collapsed and extended in accordance with theposition of said erosshead.

My invention includes the various'novel. features of construction andarral'igenient hereinafter more definitely specified.

In the drawing; the frame of the car body is supported upon the trucks 3and 3, and

tom walls-5 and t3. and the sidewalls 7. The opposite];' inclined walls9 and 10, form' a central A-shaped partition, having shutters l2 and 13,arranged to close the respective outlets between the edg s of said wallsI) and 1t) and the edges of said walls 5 and t3. Said shutters l2 and 5are respectively pivoted at 14: and 153 to the walls 9 and lth'and areoperathcly connected with the screw nut crosshead 16, by the linlt's l7and 18, which are pivotally coni'iected. with said crosshead andshutters so as to swing the latter as indicated. Said crosshiaul 16being in threaded engagement: with the vertical screw sha'l't, It thelatter arranged to be llbricated throughout. its length by grease fromthe cup 20 carried by said nut. i'aid shaft, is journaled in the bearing21 in the bar 22 extending across the car, and in the l'iearil'ig 24 inthe strut Said shalt 19 is provided with the bevel gear-'26 in mesh withthe bevel pinion which is carried by the horizontal shaft; 2t).extending laterally through the side wall 7 of the car and having the'exterior handwheel Ft). Said shall 19 is preterably protected from dustby the collapsible sleeve comprising the telescopic sectionsSpecification of Letters Patent.

1909. I Serial No. 490.485.

153. The upper section of said sleeve being secured to said strut 25.and the lower section being secured to said crosshead 1t3;-rotar v'movement of said shaft 1!) causes said sections to slide within oneanother as the said crosshead'is raised and lowered. A similar sleevemay be provided between said I crosshead and the shaft bearing 21,

I do not desire to limit myself to the pre- .cise details ofconstruction and arrangement above described, as it is obvious thatvarious modifications may be made therein without departing from theessential features of my invention as dctined in the appended claims.
